You have an OEM edition of XP and are, according to the licence, only supposed to use it on the computer it came with. I'm not sure if this particular disk will work with a new computer but it is certainly worth a try. Good luck and I hope you can use it.
Up until pretty recently the older Win 2K was selling at almost the same price as Win XP Pro, probably because it does not come with an activation system. I bought an OEM copy because it's a good OS and I can use it on all my computers and reinstall as often as I have to without having to ask permission from Micro$oft.
